Kidneys are important in preventing anemia. The kidneys make a hormone called EPO. This hormone tells the bone marrow to make red blood cells. When kidneys are diseased, they can have trouble making the EPO. When this happens, red blood cell counts drop and you can have anemia.
Anemia could occure in the early stages of kidney disease, when we still have 20 percent to 50 percent of our normal kidney function.
A healthy kidney produces the hormone called erythropoietin(EPO). This hormeone stimulates the bone marrow to produce the proper number of red blood cells.
As we know, red blood cells carry oxygen to vital organs. Disfunctional kidneys don’t produce enough EPO. As a result, the bone marrow produces a smaller number of red blood cells.
Not only a disfunctional kidney coud cause. Anemia can be caused by other causes, that include blood loss from hemodialysis and low levels of iron and folic acid.
